formed until the unit lengths or strips of- 16 pile forming materialhave been threaded through the double thickness of material along thewhole or part of the length of the same, by a reaching in tool, pricker,needle, pile fixer or the like operated either manu- 2o ally ormechanically and so that when the respective loops are flattened out,the ends of the pile forming material lie on the top face of thefoundation material, while a small portion at the centre of each stripor length is at the back of the same or fixed therein.

The invention will be more particularly described by the aid of theaccompanying drawings wherein Figure 1 is a transverse sectionalelevation of one form of machine constructed according to the inventionand with the parts in the set position for the insertion of the pileforming material.

Figure 2 is a front view of Fig. 1 with part of the rug removed to showmore clearly the mechanism.

Figure 3 is a detail plan view showing one form of locking mechanism forthe foundation fabric feed roll and automatic release therefor.

Figure 4 is a side elevation of the machine.

Figure 5 is a view corresponding to the left hand end of Fig. 1 with thefront bar moved out of engagement with the rug after the insertion of acomplete row of pile strips,

while Figure 6 is a corresponding view but 50 showing the pusher bar inits forward position after just pushing, said row. of pile strips clearof loop forming'mechanism.

In carrying the invention into effect according to one convenient manneras illustrated, a frame is provided comprising side members a, asupported on the base members I), b and formed with guides a a toreceive be equal to, greater than, or less than the maximum width of rugor the like to be produced.

Means are provided to intermittently raise and lower the plate 0, saidmeans convennions on the ends of the plate c. @One disc at is formedwith peripheral teeth meshing with teethonv a gear wheel 7 rotatablymounted on the frame a and having a handle f rigidly attached thereto bymeans of which a part rotary movement can be imparted to the shaft tocause the plate ,0 to rise or fall according to the direction of theturning movement imparted thereto, but it will be understood that anysuitable mechanism may be used for this purpose.

A roll of foundation material orbacking or warps, for instance, canvas 9is carried by a spindle g rotatably mounted in the frame I) and saidcanvas is led over the ten;- sioning roll m rotatably mounted in theslots a in the frame a; so as to be capable of being drawn intofrictional engagement b the weight m and cord 'm. with the roll a, thenunder the roll n to the feed roll p and over the plate a. I The top edgeof the plate 0 is notched or otherwise adapted to form openings c forthe passage of the strips h of pile forming material through the pleator loop g of canvas formed by the plate a when in the raised position.The before mentioned plate guides a, a extend across the machine,-

as shown, or alternatively a rod or rods may be mounted on one or bothsides of the plate 0 to limit the falling movement of the canvas whensaid plate is retracted, and thepleat g is held firmly at both sides tothe plate a vertically movable plate 0 extending across the machine forthe desired widthwhichmay along lines below the notches 0 by cross barsor the like carried by lever arms connected to a relatively fixed partof the machine. The front cross bar 5 is carried by lever arms ipivotally connected at i to the frame a and bearing on the peripheriesof cam dlscs j, j, keyed to the shaft e, and normally rerelatively to"cams. j, 7', springs k being attached at each end to the respectivelever arms 2', Z to maintain the same in contact with the respectivecams j, 7' which are formed and timed to move the respective lever armsto actuate the cross bars 2', Z in correct sequence as hereinbeforeexplained. One of the discs d is also geared to the roughened feed roll1), preferably by a link 12* coupled to a lever 72 carrying a pawl pengaging ratchet teeth on the ratchet wheel p? keyed to the roll axle,so that the latter is rotated during the rising movement of the grid tolet off sufiicient canvas to form the next pleat or loop.

The canvas 9 being formed and retained in a pleat g or loop on the grid,as seen in Figs, 1 and 2, the strips h of pile forming material can bereadily and quickly inserted through the doubled fabric by means of areaching in tool passed therethrough and through the notches in theplate a so that-when said strip of pile is placed in the eye, hook, or

jaws of the tool it may be drawn through, and the mid portion gripped bythe double thickness of said fabric.

tool actuated by hand, or if desired means may be provided to actuatethe latter mechanically.

Assuming the grid plate 0 to be raised and a row of pile formingmaterial inserted in the pleat of canvas so formed then the shaft 6 isturned by means of the handle f in the direction to lower said gridplate. Immediately the turning movement commences the respective cams jactuate the lever arms 11 carrying the front rod 71 and moves'it awayfrom the grid 0 for a sufificient distance to clear the added row ofpile, as illustrated in Fig. 5. Simultaneously with such movement of thefront gripper rod, the grid 0 begins to descend and at or near the endof its downward stroke the cams 7' permit a forward movement-of thelever arms 1 due to the tension of the springs lose that the rear pusherbar Z moves forwardly to push the last inserted row of pile under thefront rod 71 and leaves a fresh length of canvas across the grid plate 0as seen in Figure 6 ready to be formed into a' pleat 'orloop when theshaft e is turned in the reverse direction and the parts moved back tothe operative pocanvas forward.

The cam disc or discs' vmay be turned by hand and the reaching in sitionshown in Fig. 1 in reverse order. During the lowering movement of thegnd c the'lever p is raised and the pawl p rides idly over the pawlwheel p, but during the reverse movement said pawl engages the ratchetteeth so that motion is imparted to the roll p to feed the requisitelength of The reaching in tool'for inserting the pile forming materialthrough the slots or perforations in the loop forming mechanism may beof any suitable form such as a pricker,

needle 'or pilefixer according to the nature of the material being usedand may if desired be mechanically actuated. In one form of theinvention the device constitutes gripping jaws which may be opened byhand or other means after the pile fixer has passed through thefoundation material to allow of the insertion of the pile formingsubstancei The pile fixer on its return movement carries the pilematerial with it and draws it through the loop in the foundation canvas.

The operative stands in front of the machine and a tray 1- is providedto hold a supply of pile forming material in'a convenient position foruse, said tray usually being di vided by partitions to formseparatecompartments to hold different coloured pile strips.

To ensure that no movement of the foundation canvas takes place duringthe comparatively heavy strain occurring at the moment of insertion ofeach strip means may be provided to positively prevent any such move-'ment and this is conveniently effected by a locking bolt 8 carried by alever arm 8 and adapted to engage holes formed in the side of a lockingplate or disc p keyed to the axis of the feed roll p, and spaced apartfor a distance corresponding to the len h of the desired intermittenttraverse 0 the canvas. Said lever is under the influence of a spring 8on a bolt s hsecured to the frame of the machine and passing through ahole in the lever, said bolt also carrying a tubular stop 8 to limit theinward movement of the lever, the spring 5 normally tending to move itto force the bolt 8 into engagement with one of the apertures in theplate p but is moved to retract said bolt by a plunger t fixed to thegrid plate a engaging the end of said lever during the upwardmovement ofthe plate 0, said end being inclined to the longitudinal plane of themachine to cause the requisite retracting movement. The extreme end ofthe lever s is also inclined transversely, and the plunger t is slidablymounted in a cylindrical casing 25 a spring being provided nor-,

mally actin to force the plunger outwardly but permitting the same toslide inwardly as it contacts with the transversely inclined end of thelever 5 during the downward movement of the grid 0 without imparting anymovement to said lever.

It is to be understood that the improved machine may be operatedmanually or by' power, and that where specific driving gears oractuating mechanisms have been described these are only given by way ofexample since there are other mechanisms or groups of mechanisms whichcan be employed to give the same effect.
